Programming the EEPROM
236
ATmega162(V/U/L)
Figure 98. Programming the Flash Waveforms
Note:
The EEPROM is organized in pages, see Table 107 on page 233. When programming
the EEPROM, the program data is latched into a page buffer. This allows one page of
data to be programmed simultaneously. The programming algorithm for the EEPROM
data memory is as follows (refer to “Programming the Flash” on page 234 for details on
Command, Address and Data loading):
1. A: Load Command “0001 0001”.
2. G: Load Address High Byte (0x00 - 0xFF).
3. B: Load Address Low Byte (0x00 - 0xFF).
4. C: Load Data (0x00 - 0xFF).
5. E: Latch data (give PAGEL a positive pulse).
K: Repeat 3 through 5 until the entire buffer is filled.
L: Program EEPROM page
1. Set BS to “0”.
2. Give WR a negative pulse. This starts programming of the EEPROM page.
3. Wait until to RDY/BSY goes high before programming the next page
RESET +12V
RDY/BSY goes low.
(See Figure 99 for signal waveforms).
